The Genie 74872GT is a genuine OEM Counterbalance Valve, 3000 PSI designed for Genie telescopic and articulating boom lifts, including the S-60, S-65, S-60 XC, S-60 TRAX, S-65 TRAX, TZ-34/20, TZ-50, Z-60/34, Z-135/70, and ZX-135/70. As a direct OEM replacement, this valve is built to the same specification as the original component installed at the factory, ensuring it integrates seamlessly into the existing hydraulic circuit. Cross-reference part number 74872GT against your Genie parts manual to confirm fitment for your specific machine serial range before ordering.
Key Features
- Rated to Spec at 3000 PSI — This valve is factory-rated at 3000 PSI, matching the hydraulic pressure rating of the original component for correct load-holding performance.
- Genuine OEM Construction — Sourced directly from Genie, this counterbalance valve is manufactured to the same material and tolerancing standards as the part it replaces, with no deviation from original design intent.
- Direct Hydraulic Drop-In — Designed to install into the existing valve block or manifold port with the same thread form, body profile, and flow path as the original, keeping installation straightforward.
- Wide Boom Lift Fitment — Fits a broad range of Genie S-series telescopic booms, Z-series and ZX-series articulating booms, and TZ-series trailer-mounted booms, covering both standard and specialty variants including XC, HC, and TRAX models.
- Critical to Controlled Load Holding — A properly functioning counterbalance valve prevents uncontrolled boom drift or descent under load, which is essential to the safe and predictable operation of aerial boom lifts.
A counterbalance valve is a hydraulic control component that holds a load in position by preventing fluid from escaping a cylinder until a deliberate, controlled pressure signal is applied from the opposing side. On boom lifts, this valve is what keeps the boom arm from drifting or dropping when the operator is stationary or when a hydraulic line experiences a pressure loss. When a counterbalance valve wears, leaks internally, or fails, the boom may creep downward under load or respond erratically to commands — conditions that compromise both operator safety and machine reliability. Replacing a faulty valve with a genuine OEM component restores the hydraulic circuit to its designed operating behavior.
